The section for Imaging and Structural Analysis (ISA) in the Department of Energy Conversion and Storage at the Technical University of Denmark (DTU Energy) is seeking a candidate for a PhD position in Modelling of charge carrier generation and transport in 3rd generation solar cells.

At DTU Energy, we have considerable experience with development of 3rd generation solar cells, specifically as regards scale-up to devices that may be manufactured at high speed in large volume.
To become truly competitive as an important part of the energy supply in the future society, relying entirely on sustainable energy, we must acquire a better understanding of the fundamental processes of charge generation and transport in 3rd generation solar cells.

At DTU Energy, we are leading experts in characterization of the crucial nanostructures governing solar cell performance, but in order to model and manage charge generation and transport in solar cells, we need to understand not only the static structures, but also the dynamic properties of the system. See also below for a further description of the department and the research section.
This is a fully funded position offered by DTU Energy with all employee benefits.

Responsibilities and tasks

  • The PhD candidate will apply existing models of charge carrier generation and transfer in polymer solar cells and correlate the results with ultrahigh resolution 3D data for nano-structure of the absorber layer, electrodes and interfaces. Ideally, the models should be optimized directly against data providing macroscopic photo-electrical parameters for the analysed device. Secondly, a similar modelling framework could be established for kesterite solar cells, contributing to an ongoing collaboration with researchers at Imperial College. The goal of the project is to provide an analysis of the critical structure parameters that must be controlled at solar cell processing to achieve the optimal performance of the large-scale devices.
  • In order to identify critical structural parameters for controlling the processing of polymer and kesterite solar cells, we ultimately aim for correlation of full 3D modelling with 3D structure and performance data for kesterite and/or polymer solar cell devices.
  • The project constitutes a central part of SEEWHI, a 5 year project, funded by the European Research Council and aimed at a breakthrough in high-efficiency, large scale 3rd generation solar cells. 
Candidates should have a master's degree in Physics, Chemistry or a similar relevant degree with an academic level equivalent to the master's degree in Engineering.

Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.

  • The assessment of the applicants will be made by Professor Jens Wenzel Andreasen, Head of Section Luise Theil Kuhn, Professor Jenny Nelson and Professor Natalie Stingelin, Imperial College, London.
  • The candidate should have a background in physics or theoretical chemistry.
  • We welcome experience and qualifications in computational materials modelling. 
We offer
We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the World.

Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.We are currently present on both Risø Campus, close to the town of Roskilde, and Lyngby Campus, north of Copenhagen. In 2019, the entire department will be moving into new facilities at Lyngby Campus.

The main workplace will be at DTU Energy, Risø Campus, Denmark.
